CX-PA1120
The CX-PA1120 is a 120 W amplifier unit equipped with a built-in 10-zone speaker selector, designed for the CX-1000 series IP communication system. It allows audio broadcasts from each intercom station and audio interface to each speaker zone. By registering audio files in the unit's built-in memory, Chime broadcast and EV broadcast can be made. It is equipped with 2 analog inputs, 1 recording output, and 10-zone speaker output which is individually controllable. The input and output volumes can be ad justed using the front panel-mounted volume knobs or by software. The sound quality of the input and output can also be adjusted by software. The CX-PA1120 is equipped with 24 V DC emergency cutoff input function, allowing it to be linked with emergency evacuation broadcast equipment.
It features a built-in ANC function that automatically adjusts the output volume according to the ambient noise when an ANC sensor microphone is connected. Even if the connection to the System manager is disconnected, emergency all-zone broadcasts can be made using the unit's audio input and output. Broadcasts and various functions can be started and stopped using the front panel-mounted direct keys.
